ZCZC NFDSPENES ALL SPENES CAZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 11/30/12 0011Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-15 2330Z JANKOT . LOCATION...CALIFORNIA... . ATTN WFOS...MFR...STO...MTR...EKA... ATTN RFCS...CNRFC... . EVENT...NEXT ROUND OF HEAVY PRECIP . SATELLITE ANALYSIS AND TRENDS...BLENDED TPW PRODUCT CONTINUES TO SHOW ATMOSPHERIC RIVER STRETCHED ACROSS THE CENTRAL PACIFIC AIMED DIRECTLY INTO N CENTRAL CA WITH CORE OF PLUME RUNNING IN EXCESS OF 1.2", WITH A MORE GENERAL .9-1.1" OVER THE DISCUSSION REGION. NEXT MAJOR S/WV IMPULSE CAN BE SEEN IN WATER VAPOR IMAGERY APPROACHING SW OR/NW CA WHICH SHOULD HELP INCREASE LIFT/UPPER LEVEL DIVERGENCE NEXT SEVERAL HOURS. IN ADDITION THE EXPERIMENTAL SATELLITE WIND PRODUCT DEPICTS A POWERFUL PACIFIC JET WITH A MAX OF 135 KNOTS NOSING INTO NW CA PROVIDING ADDITIONAL DYNAMICS TO ENHANCE RAIN RATES THROUGH 6Z. IR IMAGERY HAS SHOWN NEW ENHANCEMENT AHEAD OF SHORT WAVE IN NW CA AS SW FLOW HAS INTERACTED WITH TERRAIN TO PRODUCE HEAVIER PRECIP. ANTICIPATE RATES OF .25-.5"/HR IN HEAVIEST BANDS WITH ISOLATED .75"/HR RATES POSSIBLE, ESPECIALLY IN OROGRAPHICALLY FAVORED SPOTS. . AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED BELOW IN APPROXIMATELY 10-15 MINUTES. . SHORT TERM OUTLOOK VALID 0030-0630Z...HIGH CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...EXPECT SW FLOW TO CONTINUE TO ADVECT DEEP PACIFIC MOISTURE INTO DISCUSSION REGION THROUGH 6Z AND BEYOND. MOD TO HEAVY PRECIP SHOULD BE THE NORM WITH .25-.75"/HR RATES IN BEST BANDS. OVERALL EXPECT 1-2" AMOUNTS NEXT 6 HRS WITH OROGRAPHICALLY FAVORED SPOTS AS HIGH AS 3". . ....NESDIS IS A MEMBER OF 12 PLANET.... .
